How We Measure Spiders
It is important that you know what to expect when your new tarantula arrives. Understanding how we measure spiders will help you better prepare for your new addition.
Spiders are measured as if they were stretched out. A diagonal measurement is frequently used, crossing the spider from the tip of the top leg to the tip of the bottom leg. Examples of how we measure can be seen below.
Please keep in mind that when your spiderling arrives, it may look much smaller at first because it will likely not stretch out until it feels comfortable.
